There are two falsehoods your argument is presenting: > Adding arbitrary, unfair stipulations to a principle defeats the purpose of having principles. > I don't understand how anyone could trade something as eternal and beautiful as body of principles into something as common and detestable as a body of exceptions. Neither of these things are occurring. The argument you present is a mix of two straw man statements and a bit of slippery slope for both. The stipulation is far from arbitrary - it's in direct response to negative discrimination at other related levels. If we are talking justice and fairness, this is a positive move to some (not all, hence grey area). Those with more opportunities inherent in a system for arbitrary reasons do not have those opportunities justly. This policy is an attempt at redistribution of arbitrarily gained opportunity. To the second, there are many flaws. First, the original principle you listed has an exception itself ("for a job in a role which is not reliant on sex-differentiated characteristics")! Adding a stipulation is a change to the principle, not an abandonment of all principles or even the single principle itself. Exceptions are incredibly important in many cases and are not an argument against a specific exception itself. Additionally, even if we accept the arbitrary "eternal beauty" of principles, the "common detestability" of exceptions, and the binary between them, there is no requirement for all of one or the other. It's just not logically sound. We can have many of one and a few of the other, half and half, etc. Again, I am not even staking any of these claims on the specific exception, which is a very strong moral grey area. But it's a very understandable and logically sound side. The question becomes one of restorative justice, not one of "principles and exceptions". I think your argument is playing towards a wish for the world and morality to be absolute and clear when we know the world is far from that every time we look at situations that break hard principles once held.
